Merge tag 'irqchip-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Merge irqchip updates from Marc Zyngier: - A number of embarassing buglets (GICv3, PIC32) - A more substential errata workaround for Cavium's GICv3 ITS (kept for post-rc1 due to its dependency on NUMA)
